What Triggers a ROBS Audit?

A ROBS audit is not triggered by one public score, one provider name or one magic fact. Public IRS materials support a narrower answer: Employee Plans examines retirement-plan operations, uses centralized case selection, and may select returns through information returns, prior-exam studies, compliance projects or reliable outside information. The ROBS project shows that missing Forms 5500, 5500-EZ, Form 1120 and plan or corporate records were used to start compliance checks, not that those facts guarantee a later examination.^[S1][S2][S4]

Use the word audit only for an examination. A compliance check, ordinary notice, DOL inquiry, participant complaint, Form 5500 correspondence or corporate tax letter can be serious and is not the same procedure. That distinction controls response deadlines, correction options, representative authority and privilege planning.^{[S3][S4][S5][S7]}

The first step is naming the contact correctly. Different agencies, units and letters ask different questions.

The IRS ROBS project began in 2009 to define compliant and noncompliant traits, identify noncompliant ROBS plans, take corrective action and design compliance strategies. Its initial compliance checks focused on companies that sponsored a plan and received a determination letter but did not file Form 5500, Form 5500-EZ or Form 1120. The contact letter asked about plan status, contribution history, rollover or direct-transfer information, participants, stock valuation, stock purchases, business information and missing filings.^[S1]

The same source identifies observed problems: many failed or failing businesses, missing annual plan or corporate returns, incorrect advice about the one-participant Form 5500-EZ exception, amendments that blocked other employees from stock rights or participation, coverage and discrimination issues, discriminatory employee participation or stock-right restrictions, benefits-rights-and-features issues, promoter fees, valuation of assets and failure to issue Form 1099-R when assets are rolled into the ROBS plan. Those are records to reconcile and issues that can lead to examination or referral. They are not a public trigger algorithm and should not be turned into avoidance promises.^{[S1][S8][S9][S10]}

Audit readiness means the sponsor can tie plan, corporate, payroll and tax records together. It is not an attempt to hide signals. The most useful file is organized by document source, filing year, participant and transaction date.

Legitimate business losses, a provider change, owner employment, adding employees, using a ROBS with an SBA loan, a single late filing, a valuation change, a distribution, or a payroll correction does not automatically prove audit selection. Each can create documents that should match across the plan, corporation, payroll provider, tax preparer and administrator.^[S1][S2][S4]

The safer framing is document readiness. If a fact has a return line, participant impact, fiduciary approval, valuation effect, cash movement or related-party dimension, preserve the record and reconcile it. Do not call it a trigger unless an agency source says the fact selected the case.^[S1][S4][S7]

An IRS revenue agent examination starts by mail in the ordinary revenue-agent sequence described by IRS before any visit. IRS scam guidance says the IRS normally makes first contact by U.S. mail, revenue agents contact taxpayers by mail before calling about an audit, and revenue agents carry both a pocket commission and an HSPD-12 card for in-person identification. Unexpected pressure, threats, social media direct messages, payment demands and requests for personal or financial information are scam warning signs.^[S5][S6]

Publication 1 says many examinations and inquiries are handled by mail, while interview examinations should be scheduled at a reasonable time and place. It also states that selection for examination does not suggest dishonesty and may result in no change, more tax or a refund.^[S4]

Preserve the envelope, letter, attachments, fax cover sheet, email headers if any, voicemail notes and every record named in the request. Calendar the response date, identify whether the contact is an EP examination, corporate tax examination, compliance check, DOL investigation, routine notice or scam, and route the matter to the plan administrator, provider, CPA, ERISA counsel, corporate counsel, valuation professional, insurer and payroll vendor as applicable.^{[S3][S4][S5][S7]}

Use Form 2848 when someone will represent the taxpayer before the IRS. Use Form 8821 when a person only needs access to tax information. Do not assume a provider, CPA, attorney or payroll vendor can speak for the plan, corporation or owner until the correct authorization and scope are in place. Keep a scope log that records every request, source, deadline, person assigned, production date and unresolved difference.^[S11][S12]

Do not backdate documents, destroy records, edit minutes after the fact without disclosure, invent valuations, alter payroll reports or make voluntary correction filings without checking examination status and privilege concerns. Once a plan or sponsor is under examination, voluntary correction choices can narrow, so timing and adviser coordination matter.^[S3][S4]

The matrix below is a filing and record-control aid. It is not evasion advice and it does not assign audit probabilities.

These examples use arithmetic only. They do not estimate audit odds, prove noncompliance or replace advice. The assumption in each example is that the sponsor is building a reconciliation file after discovering a possible mismatch.

Before a contact occurs, keep an annual archive with plan document and amendments, determination or opinion letter materials, board approvals, rollover confirmations, trust statements, stock subscription documents, stock ledger, valuation files, census and eligibility records, payroll registers, Forms W-2 and 941, contribution deposit proof, participant notices, Form 5500 series filings, Form 1120, Forms 1099-R, related-party agreements, loan files, provider contracts and correction memos.^{[S1][S7][S8][S9][S10]}

After a contact occurs, freeze document retention, identify deadlines, assign one coordinator, verify identity through IRS or DOL channels, separate privileged legal analysis from ordinary business records, answer the request asked, keep copies of every production and reconcile facts before offering conclusions.^{[S3][S4][S5][S7]}

Do not ignore a letter because it says compliance check rather than audit. Do not call every notice an audit. Do not submit a rushed narrative before reconciling source records. Do not promise employees, lenders, buyers or franchisors that the plan has guaranteed audit protection. Do not ask a provider to rewrite history. Do not destroy emails, payroll exports, bank statements or board records. Do not treat prevention as signal hiding.^{[S4][S5][S6][S7]}
